Application filed July as, 1911. Serial a... 141,201.

and State of Illinois, have invented a new and Improved Bearing,- 'ofwhich the following is a full, clear, and exact description.

My invention relates to bearings, and it has for its object to provideone which may be used on grinding wheel heads, and to provide solidtapering bearing members, which are adjustably secured to the heads, sothat they may be moved longitudinally when slightly worn, to fit snuglythe tapering ortion of the spindle Carrying the grin ing wheel. 4

As my hearing is constructed, it fits at all times during and afteradjustment, for there is no danger of forcing it out of alinement duringadjustment. The bearing fits naturally into position, where it is heldrigid against lateral movement while being secured, and it may thereforebe removed and replaced with the certainty that it will at all times bein alinement after adjustment. The bearing and its connections arerigid, and it is unnecessary to bend or expand them during adjustment orto secure the bearing in position. The construction of the hearingermits the use of a spindle, which may be" ardenedwithout any danger ofcold checks.

Additional objects of the invention will appear in the followingcomplete specification, in which the preferred form of the invention isdisclosed.

In the drawings similar characters of reference indicate correspondingparts in all the views, in which-- Figure 1 is a sectional plan View ofFig. 2; Fig. 2 is a sectional view, on the line 22 of Fig. 4:; Fig. 3 isa sectional plan view of the head with the frames showing the lubricantretainers; Fig. 4 is a sectional View on the line 4t of Fig. 2, and Fig.5 is a sectional view, on the line 5+5 of Fig. 2. I

By referring to the-drawings it will be seenthat a head 6 is provided,having frame members 7 and 8, which are spaced from each other, therebeing openings 9 and 10 disposed longitudinally through the said framemembers 7 and 8. Disposed in the said frame members 7 and'8 there arebearing members 11 and. 12', the said bearing members being keyed to thesaid frame members 7 and 8 by means of the keys 13 and 1 1.

ing bearing surfaces 15 and 16, which engage tapering bearing surfaces17 and 18' on the spindle 19.

It will be seen by examining Figs. 1 and 2 of the drawings that thebearing surfaces and the spindle taper away from the grinding wheel 20,which is secured to the spindle- 19. The outer terminals of the bearingmember 11 are threaded at 21 and 22, and

the outer terminal of the bearing member 12, which is disposed farthestfrom the" grinding wheel 20, is threaded at 23. A

.screw member 2 1 has an inner thread which meshes wlth the thread 21 onthe bearing member 11, this screw member 24 having a shoulder 25 whichengages the spindle 19, and the said threaded member 24, also has anadditional inner thread 26, which is engaged. by a threaded collar 27,which is disposed against the said spindle 19. This threaded collar 27serves to hold a gasket 28 in position against the threaded member 25,the gasket being provided to prevent the leakage of the lubricant fromthe hearing. The threaded member 24: also has a shoulder 29, which abutsagainst one 'end of the frame member 7. The thread 22 at the other endof the bearing member 11 is engaged by a thread on a screw member 30,this screw member 30 abutting against the frame memher 7. The screwmember 30 also has a shoulder 31, with an inner thread 32, the shoulder31 abutting against the end of the bearing member 11 and engaging thespindle. The inner thread 32 is engaged by an outer thread on-a screwcollar 33, the said screw collar 33 engaging the spindle 19, and

serving to push the gasket 34 against the shoulder 31 of the said screwmember 30. An oil cup 35 is secured to the frame mem her 7, and servesto lead the lubricant oil to the opening 36, through the top of thebearing member 11. There is a longitudi nal opening 36 through the framemember 7, there being openings 37 in the bearing member 11, whichcommunicate with the longitudinal opening 36, and which also extendthrough the inner surface of the hearing member 11. In these openings 37there are disposed lubricant retainers 38, which are preferablymanufactured of felt with thin brass strips 39 on their outer or loweredges, to keep them in shape.

In the longitudinal grooves 36, there are disposed members 40, havingresilient up- 1 The bearing members 11 and 12 have taper- Iwardly-projecting portions 41, which press against the lubricantretaining members 38 and tend to hold them yieldingly upward against thespindle 17. It will be seen that these members 40 may be readily removedfr om the frame members 7 when the screw i nember 24 has been unscrewed.The threaded terminal of the bearing member 12 is engaged by a thread ona screw member 42, this screwmember normally pressing against the framemember 8, and having a shoulder 43, with an inner thread which isengaged by an outer thread on a screw collar 44:, this screw collar 44being in engagement with the spindle 19, and serving to press the asket45 against the screw member isposed around an annular portion 46 of thescrew member 42, there is a clamping ring 47, the said clamping ring 47being secured to the frame member 8 by means of bolts 48. The framemember 8 is provided with an oil-cup 35, which feeds the lubricant oilto the bearing member 12, in the same manner as has been described withreference to feedin the oil to the bearing member 11. The spindle 19 isprovided with a shoulder 49, and it has a pro ecting terminal 50, whichis threaded at 51. Washers 52 are disposed on this terj which mesheswith the thread 51 on the terminal 50. A second nut 57 also meshes on'the'thread 51 of the terminal 50, and presses against the nut 56. A capmember 58 is disposed over the said washers 55, and this cap member 58is secured, with the thrust late 53, to the frame member 7 by means 0the bolts 59. An oil cup 60 is provided for feed- .ing lubricant oil tothe cap 58, so that the ,terminal 50 of the spindle 19 may belubricated. Between the frame members 7 and 8 there is disposed a pulley61,.which is mounted onthe spindle 19, and which is held in place on thesaid spindle 19 by means of a set screw 62.

It will be readily understood-that when the bearing member 11 wears, thescrew members 24: and 30 may be unscrewed to permit of the adjusting ofthe bearing member 11 against the tapering surface 17 of the spindle 19,and that when the bearing member 11 has been adjusted the screw members24 and 30 may be screwed in place and against the frame member 7 to holdthe bear ing member 11 in position. In very much the same manner thebearing member 12 may be adjusted relatively to the tapering surface 18of the spindle 19, while by freeing the bolts 48 the clamping plate 47may be removed permitting the adjusting of the screw member 42, on thebearing*1'2,.s0'-that when the annular portion 46 of the screw member 42is again moved against the end of the frame member 8, the taperingsurface 18 of the spindle 19 will be found to be held snugly in thebearing member 12. This having been done, the clamping plate 47 isreadjusted. The thrust plate 53, with the associate members, will holdthe spindle 19 relatively to the head 6 while these adjustments arebeing made.
